TECHNICAL FIELD

This invention relates to a system and application that organizes fileslike a three ring binder and shares it among multiple parties.

BACKGROUND

Three ring binders have been used to organize tiles for a long time.However, there are many drawbacks to the use of three ring binders,including version control, delayed information, and limitedaccessibility among a plurality of users. They can be heavy, take a lotof time to sort through, and are tough to re-arrange for large projects.Thus, there is a need tor a system that allows the organizationcapabilities of a three ring binder, but is much more efficient,dynamic, and accessible. Additionally, there is a need for a system thatprovides an intuitive interface that people will willingly accept.Therefore the present invention seeks to replace the old system in anefficient and comfortable manner.

SUMMARY

The present invention is directed to a system and method to view, edit,share, and organize files using software in the form of a computerapplication for a computing device. Embodiments allow multiple users towork on projects and documents while files are continually marked andupdated by users on any number of devices. This application has manyuses in a number of industries. For example, in the entertainmentindustry, the system and application can foe used to manage, share, andedit scripts among a large production team. However, this invention canapply to other industries where three ring binders are commonly used tostore information that needs to be organized, re-organized, anddisplayed in an appropriate fashion. In the medical field, this systemand application can be applied to monitoring patient information so allmedical personnel slay up to date on proceedings and medications ofpatients. In the government sector, this could apply to budgets andbilling, or to legislation that requires input from many sources. Instores, the system and application could be applied to inventorymanagement In education, the system and application could be applied tosharing notes on a digital handout. Particularly, this system isimportant where new material is constantly added by multiple sources andusers used to be up-to-date on the latest information.

In some embodiments, files are hosted in a database on a server in acloud computing environment accessible from the Internet. A userutilizing a software application on a computing device downloads filesto the computing device. The user may view and annotate files throughthe software application. If an updated version of the file becomesavailable, the user is notified and can review the updated version andtransfer annotations to the updated version of the file.

In some embodiments, there are varying levels of access to the files. Insome embodiments, the server comprises a user database having useraccess privileges to different files, set of files, projects, clients,or other such criteria. User access privileges may be restricted byuser, type of device, type of file, timeframe, or any other suchcriteria for limiting access. For example, an administrator couldprovide a user with access privileges to download, view and annotatedocuments of a project on up to one computing device. The user would notbe able to edit a content layer of the document or push an update toother users.

In accordance with the present disclosure, users of the computing devicewould be able to review updated document pages before replacing olderversions of documents with updated versions. In some embodiments, anannotation transfer view displays an old document page beside an updateddocument page, allowing the user to compare the documents and transferand edit any annotations before confirming the replacement a

These and other features, aspects, and advantages of the presentinvention will be apparent to those of ordinary skill in the art byreference to the following detailed description and the accompanyingdrawings.

In accordance with an embodiment of the present disclosure, multipleusers can concurrently download and view a document on multiplecomputing devices while making edits and annotations to the document.Select, users may update the document and push the updates to otherusers. Users receiving an updated document may review pages of the newupdated version and transfer any annotations horn an older version tothe updated version.

The collective environment for viewing and editing the document can beprovided and accessed in a variety of forms. FIG. 1 illustrates anexemplary environment 100 in which the present disclosure may beimplemented. In some embodiments, the environment 100 in which thedocument is accessible to a plurality of users on a plurality ofcomputing devices can be a cloud computing environment. In someembodiments, a software system for organizing and viewing informationcan be provided as a peer-to-peer application on a plurality ofcomputing devices that can communicate with a server and/or each othervia a network.

As illustrated in FIG. 1, a user at a computing device, such as adesktop computer 120A, a tablet computer 120B, or a cellular telephone120C, accesses the computing environment 130 via a network 110, Withindie computing environment 130, servers 140A, 140B can provide multipleservices. For example, servers 140A, 140B can provide access towebsites, user databases 150, file databases 150, and Interfaces fordifferent types of applications and devices. The server or multipleservers 140A, 140B can include virtual computing and/or storageresources. For example, an embodiment of the computing environment 130could use a two-tier architecture using Amazon Elastic Compute Cloud(EC2) server instances and an associated virtual database 150. Adatabase 150 holding information regarding users, clients, projects,and/or documents could be accessible from computing devices via anetwork 110, such as the internet or a local area network. Examples ofuser information include the user's name, picture, email, password,screen name, phone number, devices, profile, past work, currentprojects, and/or user access privileges. Examples of project informationinclude project title, picture, description, creation date, updateinformation, whether the project is active/inactive, availablefiles/documents, and/or users involved. This data would preferentiallybe protected by security, whereto access requires users to provide thenecessary security credentials.

In some embodiments, the server cloud may comprise a website find artapplication server for communication with client devices. For example,the website may be accessed by a user via a browser on a clientcomputer, and may provide logistical user registration, profilemanagement, project creation and payment options, and other suchfeatures. The application server, such as a Node.js App Server,communicates with all client side applications, such as an applicationon a smartphone, a tablet computer or a desktop computer. In theseembodiments, the Node.js App Server could be configured to support usermanagement centric call flows, including creating and managing useraccounts and projects globally, verifying user access information onlogin from a computing device, managing project information to send tothe user based on login information and the type of device, and/orsending and receiving document information. The Node.js App Server maystore high level summary information about each user's client/project inorder to populate information on a device's first login screen beforeentering into a specific project's detail view. The App Server may alsoprovide APIs to create/update/retrieve/collate specific, projects. APIsto store/retrieve user level annotations, and notification capabilitiesfor project updates.

In some embodiments, users may have different access privilegesregarding documents and projects. In preferred embodiments, a project isan environment on the system that may be shared amongst multiple userson multiple computing devices so that users with access privileges tothe project have access to the same files stored within thatenvironment. In some embodiments, access privileges are granted based onpredefined levels or tiers of users. For example, a user wish firstlevel access privileges may be defined as an Administrator with accessprivileges to ail functions, including updating the documents stored inthe server and changing other user's access privileges. A user withsecond level access privileges may be defined as a Reader with accessprivileges to view documents and make local annotations. In otherembodiments, a plurality of functions may be available and set forindividual users. For example, functions may include viewing projectdata, download/viewing documents, annotating documents, sharingdocuments and/or annotations, uploading revised documents, setting useraccess privileges, terminating a project, messaging other users in aproject, and the like. The user access privileges of a user in such anembodiment may toggled on or off for each individual function.

In some embodiments, as shown in FIG. 2, each project has its own set ofaccess privileges for different users. Users may have first level accessprivileges on some projects, second level privileges on other projects,and no access privileges on additional projects. For example, User X mayhave first level access privileges to Project A and second level accessprivileges to Project 8, while User Y may have second level accessprivileges to Project A and Project C. Some users may have limitedaccess privileges to only view documents and personal notes andannotations that are not shared among other user devices or the cloud.Some users may have access to modifying the document on a computingdevice, sending it to the server and distributing it to other users withaccess privileges to the project.

In exemplary embodiments, a user who creates a project has an ability todefine the user access privileges of other users and define thetermination conditions of a project. Termination of a project may be seton creation, such as by putting a time and date for a project to enduser access privileges, or manually terminate the project at any point.In some embodiments, project termination may be provided to other users.

FIG. 3 is a call diagram of a system comprising a first level user, asecond level user, and a server in accordance with an embodiment of thepresent disclosure. In this embodiment, a first level user, labeled asan Administrator 320, and a second level user, labeled as a Reader 330,interact with a server 310. In this embodiment, the server 310 hosts aglobal user database for user login and access level information andcreates a server instance, such as an Amazon EC2 server Instance, foreach project.

In step 340, a user before becoming an Administrator 320 for a projectaccesses the server 310 in order to create the project. In someembodiments, a user accesses the server 310 using a computer browser toaccess a website hosted on the server 310. In other embodiments, a useraccesses the server 310 through a software application on a computingdevice. In some embodiments, user registration in a global database is arequirement in order to create a project. In creating a project, thesystem prompts the user to enter information necessary to create theproject. For example, the system may require or request a tide, a periodof time for the project to remain active, payment, user accessinformation, a description of the project, documents to upload to theproject, and other such information. This information may be enteredwhen creating the project and/or may be updated at a later point intime. The server may generate various settings and documents based ondie information provided. Its some embodiments, once a project iscreated, the user who created the project is automatically set as anAdministrator with first level access privileges to the project.

Managing user access privileges may be done by users having thenecessary access privileges. Users may be added, removed, or have theirlevel of access privileges changed by a user having user managementaccess privileges. In an exemplary embodiment, only Administrators haveuser management access privileges, and are able to invite first andsecond level users and remove/edit access privileges of users withsecond level access privileges from the project. Readers would not haveaccess privileges to manage the project's user access privileges. In theexample embodiment, the Administrator invites a user to join a projectas a Reader in step 350. Once a user accepts an invitation as a Readeror Administrator, that user then has access privileges to view anddownload documents that are part of the project, in some embodiments,users may be part of groups in social networks, and may be invited as ateam to projects.

Project documents stored on the server 310 may be made available tousers with access privileges to the project. In the example embodiment,all users, including all Administrators and Readers, have accessprivileges to view and download documents to computing devices. However,only Administrators have access privileges to upload or updatedocuments. In the example embodiment, Administrators manage documents instep 360, which includes uploading, documents, revising documents,updating documents, and pushing revised documents to other users.

Managing documents may involve managing different versions of thedocuments. For example, a server version of a document can start atversion 1.0 and increase with every update. In some embodiments, insteadof having an incrementing version number for each document, a projectmay have a project version number in order to track changes. In someembodiments, the server may save each version individually and allowaccess to all versions of a document. In some embodiments, only thelatest version of the document is available to users. In someembodiments, an Administrator may force users to update their documents.A software embodiment of the present invention could keep track of theversion of ail relevant files in order to ensure files are up to date.In some embodiments, die server 310 automatically notifies all userswhen a document has been updated, such as through the softwareapplication or attached communication methods such as email or textmessages. In some embodiments, an Administrator pushes the document tothe user of the project. In some embodiments, a user manually queries tocheck for updates. The updating process 370 is described in more detailfurther below in the detailed description.

In an exemplary embodiment, a user would use a software application on amobile device or tablet computer in order to access documents on theserver. The software application may be operable to access the server,transmit user credentials, download and display projects and documents,annotate the document, and update the document. Depending on the user'saccess privileges to a project, the application would enable or disablevarious functions in managing the project.

In some embodiments of a software application, the software providestools for a user to mark or change the documents saved locally in thesoftware application. For instance, a user may annotate the documentusing annotation features, including adding text, drawings, shapes,freeform pen, cues/graphics, highlights, tags, bookmarks, and other suchfeatures. These features may be customizable, such as by color, fillcolor, background color, font, size, alignment, bold, underline,italics, and opacity. Tags may include pages, acts, items, slugs,people, teams, breaks, and other such information that a user may wishto mark and monitor.

In some embodiments, each document comprises a content layer and a notelayer. The content layer comprises the base PDF document, includingtext, pictures, formatting, and the like. The note layer holds theannotations of a user created on the software application. The contentlayer and the note layer may be edited independently. This is useful inensuring that edits on one layer do not affect edits on another layer.In some embodiments, different layers are stored in a single file. Inother embodiments, the content layer and the note layer are separatefiles that are called to be viewed together as a single document.

In further embodiments, the document may comprise one content layer andmultiple note layers, wherein a user viewing the layers chooses displayoptions for each layer. These display options may include whether or notthe layer is displayed, in which order the layers are displayed, stylechokes for the annotations, or the like, for example, in certainembodiments wherein a plurality of Readers annotate a single document,each Reader creates a unique note layer for the document and uploads itto the server. These note layers and the content layer of the documentare then downloaded by an Administrator, who can choose to display allnote layers over the content layer. Each note layer is tagged with theuser who created it, and its display styles may be chosen by theAdministrator. This would be very useful for editors when editing andupdating documents to know what areas to focus on and what toincorporate, as well as keeping track of which user created each note.

In some embodiments, the server version of a document comprises acontent layer with an empty note layer. An Administrator may uploadannotations to the note layer of the server version of a document. Insome embodiments, a document may comprise multiple note layers for eachuser of a project. In such embodiments, each user may be assigned a notestyle or tag to differentiate the note layers by user. In someembodiments, users may have limited access to different note layers. Inan exemplary embodiment, a user may download the content layer and themultiple note layers of a document, incorporate the note layers of thedocument into the content layer, and then upload the updated contentlayer to the server as a revised document.

FIG. 4A shows a graphical user interface (GUI) displaying a login screento a software application in order to verify user access privileges inaccordance with an embodiment of the present disclosure. A username andpassword lock verifies a user's access privileges to access documentsand projects on the server. In some embodiments, a feature allows a userto save login information or to always stay logged in for convenience.

FIG. 4B shows a Project List page of a software embodiment in accordancewith the present disclosure, wherein the projects in which a user hasaccess privileges are displayed. In this example, a user has access totwo active projects for two episodes of a TV show. Projects that havealready been de-activated can be shown by selecting the button in thetop left hand corner labeled “Active Projects” and selectingde-activated projects. De-activated projects may have restricted accessor no access to users who had access privileges while it was stillactive. Projects may be displayed or sorted based on a user's criteria,such as chronologically, alphabetically, numerically, most recentlyaccessed, or the like. Projects may also be searched, such as bykeywords or tags. The display of each project may show as many or as fewdetails as needed or wanted. As pictured, each project is shown with atitle, the last date the Project was updated, and a button to downloadall files in the Project. An additional image is displayed that isrepresentative of the project. The example image is framed in a 2 ringbinder to maintain die theme of the software replacing the features of aphysical binder.

FIG. 4C shows a Project page of a software embodiment of the presentinvention. As shown, the project page may display an imagerepresentative of the project, along with identifying information, suchas the title, date for the show to be aired, the date of the lastupdate, a list of all documents that are part of the Project, and otherinformation of which a user of the Project may wish to access. In thisembodiment, the representative picture is framed in a three-ringedbinder, keeping with the theme of a software program replacing aphysical three-ringed binder. A user taps on a document in order to viewthe document in the Document Reader.

FIG. 4D shows a sample script viewed in the Document Reader. Thisdocument may be annotated by various members of the production team, andedited and updated by select users such as a director in charge of dieproduction team. The document shown herein is of the PDF format, butother file formats may also be used. For example, text documents,spreadsheets, maps, pictures, or any other type of document that a userwould wish to display on a computing device. The document, may alsoinclude features not available in a typical paper-based three-ringedbinder, such as links to other pages or websites, music, video, andother such added functionality.

In additional to the features a document may have embedded, softwareembodiments may also include a set of tools for navigation andannotating/marking the document. As shown on the top framework of theGUI, the software embodiment provides various functions that make adigital three ring binder much more useful and convenient than aphysical three ring binder.

The functions shown in this embodiment include, but are not limited to,Menu, Revision, search, Go To, Document List, Hold, Multiple Page View,Email, Annotation, and Sections. The Menu Button as shown herein allowsa user to switch back to the Projects List Screen, view/edit a user'sprofile, and allows a user to log out, The Revision icon as shown hereinnotifies a user when an update to a Project or document is available,downloads the available update, and navigates the user to the RevisionMenu, as explained further below. The Search Button allows a user tosearch the contents of the documents. The GoTo Button allows a user tojump to a spec die item or page number. In some embodiments, a userclicking the GoTo Button is shown a virtual keyboard in which the usertypes in a desired item, and the software embodiment automatically listsmatching pages or items as the user types. The Bookmarks Button allows auser to add bookmarks to a document. These bookmarks are used to markcertain pages of documents hi order to quickly come back to those pages,for example, in the multiple page view of the document, a user would beable to choose an option to view only bookmarked pages. This allows auser to see all the pages the user wishes to return to. The Hold Buttonis used as a link to page in the document. A user can tap the BoldButton once save a place and then no matter where the user navigates,the user taps the Hold button to jump back to the saved page. The GridView is used to view multiple pages of a document for quick navigation.In some embodiments, the grid view also shows a user's notes. The EmailButton allows a user to email a copy of a document. This feature may beuseful to transfer the document to another person, especially one whomay not have access to the software embodiment of the system. This isalso useful to send a copy of a document as a backup. The AnnotateButton allows a separate set of Annotation tools to appear that allows auser to mark/edit the document. These annotations may be transferredwhen a document is updated. The Sections Button allows a user tonavigate to different documents within a single Project.

FIGS. 4E-4F demonstrate a feature designed to make the transition from aphysical three-ringed binder to a digital three-ringed binder morefluid. In some embodiments, navigation of a document may involveflipping over a page to get to the nest page. By touching the right sideof a touchscreen and dragging it to the left, the digital page of thedocument may act like a physical page by displaying a representation ofthe page bending to reveal the next page in the document. The locationof the page initially touched and the direction the user movesdetermines how the page interacts with the user. For example, as shownin FIG. 4E, a user touches the top right corner of the screen and dragsthe page to the left, revealing the right side of the page. In FIG. 4F,a user touches the bottom right corner of the screen and drags the pagediagonally up and left. This causes the bottom right portion of the nextpage to be revealed. This unique embodiment allows a user to view asection of a first page and a section of a second page without fullytransitioning from page to page. This navigational feature maintains thetheme of simulating a digital three ring binder.

FIGS. 4G-4I show an embodiment of the Grid View. In this view, multiplepages are shown at the same time in a grid. This view may includeadditional indicators to notify the user of specific properties of apage. For example, a page may be highlighted a first color to signifythat the page has annotations, a second color to signify that the pagehas been bookmarked, a third color if the page has been revised in thelast update, and any number or combination of colors for any otherproperty a user may wish to indicate. The Grid View may also haveadditional features, such as displayed in the menu bar. For example,FIG. 4H demonstrates an annotation list, displaying the annotations in adocument, their pages numbers, and their properties. A user may be ableto click on an annotation to view that page of the document. In anotherexample, FIG. 4I demonstrates a bookmark list, which only displays pagesthat have been bookmarked by the user for ease of navigation.

FIGS. 5A-5D demonstrate various Annotation Tools that may be availableto a user using a software embodiment of the present disclosure. Thesetools act similar to how a user would use a pen in a physicalthree-ringed binder in order to mark up a document. As shown in the topmenu bar, annotations tools may include, hot are not limited to,Highlight Text, Textbox Button, Freeform Drawing, Shape Tool, MarqueeTool, Cue Tray, Styles, Undo, Redo, Tag, and Bookmark.

The Style Tool, as shown in FIG. 5A, may be used with various annotationtools to customize the style of the annotation, such as in color, font,size, pattern, background, or other such styles. Each annotation toolmay have customizable styles not available for other annotation tools.The Style Tool may also show a preview of what the style looks like whenapplied. Styles may be customized before, or alter the annotation iscreated.

The Highlight Text tool may be used to select text in the document to behighlighted. A user may click this button and then click and drag afinger over text in the document. Since document text may differ when adocument is updated, highlights may not be transferred in someembodiments. In this situation, a user may need to manually highlighttext in Annotation Transfer View.

The Text box Button, as shown in FIG. 5B, may be used to type in textthat may be displayed and moved around on a page. When creating atextbox, a user may use a physical or virtual keyboard, or any othersuch input device that allows a user to type in text. In an exemplaryembodiment, a virtual keyboard appears along a lower portion of thetouchscreen of a computing device and a user types in the desired text.After text is input the textbox may be clicked on and moved to a desiredlocation on the page. Clicking on the textbox allows a user to customizethe style of the text.

The Freeform Drawing tool is used to draw or write on the documentsimilar to a user drawing on a piece of paper with a pen. In someembodiments, a user taps and drags a finger on a touchscreen to mark.the document where the finger pushes down. In some embodiments, a useruses a stylus on the surface of a touchscreen, wherein the document ismarked where the stylus touches the touchscreen.

The Shape Tool, as shown in FIG. 5C, provides a user with various shapesto draw on the document. In some embodiments, as shown in FIG. 5C, auser taps the Shape Tool, selects a type of shape, like a square orcircle, and then taps and drags a finger on the surface of the computingdevice to define the boundaries of the shape.

The Marquee Tool is used to select several annotations at once. In someembodiments, a user may select in annotation by tapping on it. In someembodiments, a user may select an annotation by enclosing it in amarquee box. When several annotations are selected at once, a user maybe presented with additional options. For example, a user may bepresented with the option to group the annotations. If annotations aregrouped, then tapping on one of the annotations selects all of theannotations. When multiple annotations are highlighted, they may beedited at the same time, such as by moving the annotations,, changingthe style of the annotations, copying the annotations, or deleting theannotations.

The Cue Tray, as shown in FIG. 5D, may include several graphics,frequently used annotations, or any other pre-made annotations a userdesires. For example, the Cue Tray may include stylized numbers, commonstage directions, or stage positions that may be used often in directingactors, as shown in FIG. 5D.

The Undo and Redo buttons allow a user to undo or redo an action thathas been taken. For example, a user may freeform draw an annotation on adocument, then hit the undo button to remove the freeform annotation.The user may then hit the redo button to return the freeform drawing tothe document again.

Additional tools may be available when selecting an annotation. Forexample, a user may choose to group annotations together, such as a textannotation with a circle annotation circling the text, in order to movethe grouped annotations together. In another example, an inspectorfeature may allow a user to view tags associated with annotations andedit the style of the annotation. These tools are just some ways a usermay manipulate a document's note layer using a software application on acomputing device.

FIGS. 6A-6F show an embodiment of the process of updating a document toa revised version. In a normal updating process for documents andprograms, older files are completely replaced by newer files without, aneed of any formal review by a user. Users can find out what changeswere made by reviewing the patch/update notes or reviewing the new file.However, the process of updating documents in this software applicationenvironment is unique, as the note layer of a document containing usercreated annotations may be preserved when updating a file from oneversion to the next. This is accomplished by having each documentcomprise at least two layers. In the example embodiment, each documenthas two layers, a content layer and a note layer, although more layersmay be used.

FIG. 6A is a call diagram of one embodiment of the process of updating adocument. Typically, a user will download a version of a document fromthe server and store it as a local document 610. The local documentcomprises a content layer 612 and a note layer 614. The content layer612 stores the content of the local document 610, while the note layerstores the annotations of the local document 610. In some embodiments, anote layer 614 starts out blank, wherein the user adds annotations tothe note layer 614 over time. In some embodiments, a user uses asoftware application to download the content layer 612 of a localdocument 610, and the software application creates a blank note layer614, in some embodiments, the note layer 614 downloaded from the serverbas the annotations of others users stored in them. In otherembodiments, the annotation layer 614 of a local document 610 is storedon a cloud and can be shared among a plurality of devices. In theexample embodiment, in step 630, a user downloads version 1.0 of adocument and stores it as a local document 610, although the version maybe any version number of the document. Once a local document 610 isstored on the software application, a user may create/edit/deleteannotations on the note layer 614 of the local document 610 in step 632.

When an update for a document is available, a user should be notified bythe server as shown in step 640 and FIG. 6B. Different notifications maybe available depending on which screen a user is on. For example, if anupdate became available while a user was not in the softwareapplication, a notification may pop up as a numbered bubble over theicon to start the software application. A notification could also bedisplayed on the Project List screen, the Project screen, or a documentscreen highlighting which. Project, document, page, or other informationwas updated. FIG. 6A shows art embodiment of an update notification whenthe user is in the midst of viewing a document. In this example, thenotification pops up over the document with a button to update thedocument or page. In addition, the Revision button on the menu bar showsa circled number one icon to notify the user chat there is anupdate/revision. When the user selects the Revision button or the buttonfrom the update notification, the user downloads the updated version, asshown in step 642, and is directed to the Annotation Transfer View, asshown in step 650.

The Annotation Transfer View displays two documents side by side, asshown in FIGS. 6C-6F. The Annotation Transfer View is useful indisplaying corresponding document pages in order to compare differencesand transfer annotations. In the example embodiment in FIG. 6C, arevision document page 626 is displayed on the left and a local documentpage 616 is displayed on the right. In some embodiments, only the pagesof the revised document 620 that are different from the local document610 are displayed. For example, pages that are different may be groupedin a revision pack and sent to users requiring updates so that the userdoes not need to download the entire document when updating. In someembodiments, only the pages of the local document 610 with annotationsand the corresponding pages of the revised document 620 are displayed.In some embodiments, a user selects what is displayed by selecting theoption, such as by selecting a Pages with Annotations Only button. Inthe example embodiment in FIG. 6C, annotation tools and the grid view isalso available to the user. If the user decides not to update thedocument immediately, the user may go back to viewing the document bypushing the “Go To Document Reader” button.

In embodiments of the Annotation Transfer View, tools are provided totransfer data from note layer to note layer or from content layer tocontent layer. In the example embodiment in FIG. 6C, the softwareapplication provides a Transfer All button. Clear All button, andReplace button. The Transfer All button transfers annotations front thenote layer 614 of the local document page 616 to the note layer 624 ofthe revised document page 626. This is similar to copying notes from onepage to another, but easier, taster, and more accurate. The Clear Allbutton deletes all annotations from the note layer 624 of the reviseddocument page 626. This is similar to erasing a page of notes. TheReplace button overwrites the local document page 616 content layer 612and note layer 614 with the revised document 624 page content layer 622and note layer 624. This is similar to removing a physical page from abinder and collating a new updated page into the binder. In someembodiments, additional types of transfer may be possible. For example,in some embodiments, a first level user may transfer annotations from anote layer to the content layer, and then upload the content layer as arevision pack.

In a typical example of using the Annotation Transfer View, a userstarts by viewing the documents side by side in a software applicationon a computing device, as shown in FIG. 6C. The user pushes the TransferAll Button to transfer annotations from the local document page 616 tothe revision document page 626, as shown in FIG. 6D. The user thenedits/adds/deletes the annotations, as shown in FIG. 6E. After the useris satisfied with how the revised document page 626 looks, the userpresses the Replace. Button to collate the new page into the localdocument 610, replacing the content layer 612 and note layer 614 of thelocal document page 616 with the content layer 622 and note layer 624 ofthe revised document page 626, as shown in FIG. 6F. This process isrepeated for each page of the local document 610 that is updated. Whilethe illustrated embodiment only displays the tools for transferring,editing and replacing components of the note saver and content layer ofa page, other tools may be available. For example, tools for insertingnew pages or removing existing pages similar to how a user infracts witha physical three ring binder may be useful to a user organizing andmaintaining a document.

Themethod steps are described herein to illustrate various embodiments fromdifferent users in accordance with the present disclosure, and are notmeant to be exhaustive or limiting.

User A, shown in FIG. 7A, is an example first level user who creates aproject. User A accesses a website through a browser on a computer andlogs in to the server at step 712. Once inside the website, the usercreates a project in step 714. In this example, the user providespayment information for the project to be active for a set time period.Once the project is initiated. User A uses software applicationsdesigned to access and view project files.

One embodiment of a software application to access and view projectfiles is an Admin Console, designed tor Administrators to download,edit, and upload project documents and manage user access privileges. AnAdministrator will log in to such a software application in step 740 toauthenticate user access privileges to various projects. Managing useraccess privileges is an important step in sharing the project withvarious users. User A may invite users such as User B and User C to theproject in step 742, and edit their access privileges in step 744. Insome embodiments, the invitation indicates the access privileges theuser will receive when the invitation is accepted. Another importantfeature its this software application is the ability to managedocuments. An Administrator will initially upload documents to be storedon a server in step 748. Other users using their devices will downloadthose documents and view them on their devices. Meanwhile, theAdministrator may choose to edit the documents in step 750. Thoserevisions may be uploaded to the server and pushed to the other users ofthe project in step 752. This is a continual process of updatingdependent on what the Administrator decides until the project isde-activated.

Another embodiment of a software application designed to access and viewproject tiles is a Reader Application. The Reader Application isdesigned to be used by all users to download and display projectdocuments, and provides tools tor the user to annotate each documentwithout changing the content layers of the documents. For example, thisapplication may take the form of a tablet computer application to savedocuments from a server and view then on the display. A user will log into the Reader Application in step 760 to authenticate the user accessprivileges to various projects. Projects available to the user will bedisplayed in the application, and the user may elect to download theproject's and associated documents in steps 762, 764. The user annotatesthe documents in step 766, making notes on a note layer of the documentin order not to alter the content layer of the document, allowing easiertransfer of annotations between versions of documents. When an updatedversion is detected from the Reader Application in step 768, the usermay download a revision pack to update the document to the newestversion. This allows a user to compare the previously downloadeddocument with the revision pack side by side in the Annotation TransferView. The user transfer the annotations to the revision pack in step772, edits the annotations on the revision pack in step 774, and thenreplaces pages of the old document with the revised pages of therevision pack.

User B, shown in FIG. 7B, is an example Administrator who is invited tothe project. User B differs from User A in that User B did not createthe project by accessing the website. However, after User B receives theinvitation in step 122 and accepts the invitation in step 724, User Bhas the same access privileges to the project as User A, includingaccessing the various embodiments of software applications to access,view, and edit projects.
